Letters Patent No. 109,936, dated December 6, 1870.

IMPROVEMENT IN CORN-PLANTERS.

The Schedule referred to in these Letters Patent and making part of thesame.

I do hereby declare that the following is a. full, clear,

and exact description thereof, reference being had to the accompanyingdrawing.

Figure 1 s a perspective view of myimproved cornplanter.

Figure 2 is a bottom view of lig. 1, partly insection.

Figure 3 shows the 'discharge-aperture, the cap bcing removed.

Figure 4 is an inside View of the cap.

Figures 5 and 6 are transverse vertical sections, taken on the line a:n; of' iig. 2, the rst showing the discharge-aperture open, and thelatter closed.

Similar letters ofreference refer to indentical parts in each of Ithefigures.

To' enable others skilled in the art to which my invention relates tomake and' use the sam-e, I will proceed to describe the construction andoperation. Y

In .the annexed drawing forming a part ot' this specificationy Arepresents a cylinder, within which the seed is to be deposited'which itis desiredto Ahave sown.

It has a tube running through its center for thereception of thehoe-handle.

At the lower under side of the seed-cylinder there' is inserted a bung,B, having an opening in it, which has arranged upon one side-a brush, b,as shown iu tig 3. A

Over these parts the cap C is placed, which has an opening in'its face,as shown in iig. 2, and by dotted lines in fig. 4.

Within this cap rotates the slide D, having an aperture which can beincreased or diminished, so as to hold more or less seed, by means ofthe guide d, which has a slot in it and is secured to the slide, asshown in fig. 4. V

The slidev has a hook or eyelet, which Aprojects i through a slot in thecap C, to the shank of which one end of spring E issecured, the otherend `being fastened on the reverse side of the cap.

The action ot' this spring upon the seed-slide D is suoli as to hold itclosed, as indicated by dotted lines in tig. 2.

The dotted lines upon the face of the cap C indicate the position of'tbeaperturein the slide D where the same is closed.

The brush b is to act as a scraper to the aperture in the slide D, asalso to provide a pliable surface vto prevent the corn from gettingbetween parts B and D, thus clogging and preventing free action.

The operation may be stated as follows:

The parts being in position, as shown in figs. 1 and 6, seed will falland ll the apertures in the part 'B and the seed-slide D, the slide isthen drawn into po,-` sition, as shown in iigs. 2 and 5, the aperturebeing thus brought immediately over the opening in the face of the capG, and the seed falls to the ground.

The draft upon the slide is then slackened, when the action of thespring E brings the parts to theirnormal position.

Its simplicity, durability, and certainty of performing the purposeforwhich it is designed must oommend it to those interested in the branchof industry to which it relates. y,

Having thus described my invention, y

What I claim, and desire to secure by Letters Pateiit of the UnitedStates, is-

The arrangement of the cylinder A, bung B, brush b, cap C, -slide D,guided, and spring E, substantially as shown and specified, and for thepurpose 'set forth.

In testimony whereof', I have signed my name to this specification inthe presence of two attesting' witnesses, this 1st day of August 1870. i
